Dielectric properties of an antiferroelectric/ferroelectric BiFeO3/Co bilayer structure

Insight into dynamic magnetic properties of YMnO3/FM bilayer in a time-dependent magnetic field

“…A comparison is made with those in Ref. [41], and there is a high similarity between the two in the effect of bias field on TB.…”

“…Similar phenomenon of U curves can be seen in Refs. [36,37,41]. The χ curves of the system is displayed in Fig.…”

“…The χ curves of the system is displayed in Fig. 2(c), as shown in the figure, every curve has a peak which corresponds to a certain temperature, which is called the blocking temperature TB [41].…”

“…From a physical point of view, Q exists under the competition between temperature, exchange interaction and magnetic field, and the larger Jcd is more dominant in the competition among the three. It can bind the spin to a fixed state which is not easy to change, thus leading to the stability and invariability of Q [33][34][35][36][37][38]41]. In Fig.…”

“…In our previous works, much effort was made on the magnetic and dielectric properties of the low-dimensional mixed-spin nano-systems using Monte Carlo simulations [33][34][35][36][37][38]. In addition, such BiFeO3/FM bilayer system was also investigated [39][40][41]. However, to the best of our knowledge, little energy is devoted to the dynamic properties, such as dynamic order parameter, internal energy, susceptibility, and dynamic hysteresis behaviors of YMnO3/FM systems.…”
